Gilgun will play new character Rudy, following the departure of actor Robert Sheehan, who played Nathan in Series 1 and Series 2.
Lauren Socha, Nathan Stewart-Jarrett, Antonia Thomas and Iwan Rheon will all return for the new series, which will run for 8 episodes.
Channel 4‘s press-release reveals: “New kid on the block Rudy gets a rude awakening in his first few days of community service, learning that with the keys to the infamous locker comes a great deal of running and screaming and, in some instances, bloodletting. But that really is the least of his worries. More pressing is just how to keep his secret superpower, well, secret. And is it super? As in from the A- List?”
It continues: “The rest of the gang are also back with all-new powers. But just how did that trade off with Seth (Matthew McNulty), the superpower dealer, go down? You would hope that at least one of them has a power approaching something halfway useful. You would hope… Is Simon any closer to fulfilling his destiny as Superhoodie? And just where does he learn to do all that nifty parkour? With Seth still trading powers, zombies on the loose, havoc being wreaked with events from the past and even more havoc being wreaked in the present, things haven’t got any quieter for our gang…”
Series 3 will air later this year. A new Misfits soundtrack album is released this week.
